ansibleでEclipseの自動インストール

ansibleを使って、Ubuntu(Linux + GNOME)に、Eclipse 4.5(Mars)をインストールして、必要なEclipseプラグインを自動インストールするサンプル。
Eclipseプラグインは、削ったり追加したりしてやってください。リポジトリ（Update Site）も、プラグイン自体も、カンマ区切りです。
もっと、綺麗に書こうとすれば、書けるとは思う…

ちなみに、インストール先は、/opt/eclipse/配下にバージョン毎にディレクトリを作って、alternativesで、デフォルトを切り替えてます。

```:yaml
- hosts: 127.0.0.1
  connection: local
  become: yes
  tasks:
    - apt_repository: repo='ppa:webupd8team/java'
    - name: Autoaccept license for Java8
      debconf: name='oracle-java8-installer' question='shared/accepted-oracle-license-v1-1' value='true' vtype='select'
    - name: Install Java
      apt: name={{item}} state=latest
      with_items:
        - oracle-java8-installer
        - ca-certificates
        - oracle-java8-set-default

    - stat: path=/opt/eclipse/eclipse/eclipse
      register: installed_eclipse
    - get_url: url=http://ftp.jaist.ac.jp/pub/eclipse/eclipse/downloads/drops4/R-4.5-201506032000/eclipse-platform-4.5-linux-gtk-x86_64.tar.gz dest=/tmp/eclipse-platform-4.5-linux-gtk-x86_64.tar.gz

ちなみに、Gnomeのデスクトップエントリーは、こんな感じ。

```eclipse.desktop
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Name=Eclipse
Icon=eclipse.png

```

多分、インストール先とかダウンロード元とかをansible_distributionで切り替えてやれば、色んなプラットフォームに応用出来ると思う
